w. HbFER FASTENER ATTACHING MACHINE Filed Dec. 22. 1928 INVENTORPatented Oct. 22, 1922 UNITED STATES PATENT OFFICE FASTENER-ATIACI'IINGMACHINE Application filed December 22, 1928, Serial No. 327,912, and inGermany March 23, 1927.

This invention concerns a machine for securing fastenings, includinghinges and similar fittings to bones made of wood, card-- board, thinsheet metal and other suitable material, for instance cigar bones,cardboard boxes, etc., provided with a flat lid and with a lid providedwith a rim, by inserting and bending over long and narrow tongues,

which are made in one piece with the fastenio ings, hinges etc., or byinserting the tongues over their whole length without the bendingoperation.

The invention is shown, by way of eX- ample, in the drawing, in whichFigure 1 is a front elevation,

Figure 2 a side elevation partly in section,

Figure 3 a plan partly in section,

Figure 4 a section taken along the line A-B of Figure 2.

Figures 5 to 14 show details.

The machine which, according to the drawing, is constructed in the form,of a one-armed press with a machine body 1, a base plate 2 and isprovided with a doublearmed lever 4, secured by bolt or bolts 3, whichlever carries on the one side a transverse rod 5 and on the other side acounterweight 6, and is adapted to be partly rotated through thedraw-rod 7 by "footpressure or in some other way. On the transverse rod5 are secured, in an adjustable manner, short arms 8, and these areconnected by joints with. vertical spindles 9, which are verticallylocated in guides 10 and carry at the lower extremity a driver 11. Theguides 10 are arranged in an adjustable manner on a transverse slidebody 12, connected with the machine body 1, and are adjusted laterallythrough screw spindles 13 disposed in the said machine body, whichspindles are connected by a threaded nut 14: with the guides 10.

Under each of the drivers 11 a carrying member 15 for the fastenerholders is mounted on the guide-rods 16 which are set each in across-head 17 connected with the spindles 9 and are inserted verticallyin the guides 10. Between the latter and the members 15 a spring 18 isfitted on each of the guide-rods 16. For accurately guiding the members15,

tached as shown in Figures l, 9 and 10.

The

tastenings, hinges, etc., have long narrow tongues, and for thesecorresponding gro 22 are provided in the fastener holders 20.

grooves 22 the fastenings,

hinges. etc., are accurately guided during the attaching operation.

In the base-plate 2, as shown in Figures 1 to 8 and 6, underneaththefastener holder 20 an anvil -6 is fitted in a displaceable manner, onwhich is placed, for instance,

the

cigar box as. Fi 'ures 1 and 2 or an other r '3 3 y Ob ect to beprovided with fastenings,

hinges, etc.

In accordance with Figures 1 and 2,fastening members 25 as per Figure 12are to be attached the cigar box 24 or the like, which members areprovided with long pointed tongues 26. In the fastener holders 20 thefastening member 25 is inserted for this purpose and then, by tootpressure or otherwise,

the lever 41: is drawn downwards with front arm. The spindles 9 arethereby moved downwards in a precisely vertical direction with thedrivers 11, the gu1de-rods 16 and the he members 15 with. the fastenerholders 20 and the fastening members 25 etc. disposed therein, until themembers 15 rest on the cigar box as or the like. The spindles 9 with thedrivers 11 then continue their downward movement alone, whereby thefastening members 25 are pressed through the fastener holders, thetongues 26 of the latter are insorted in the cigar box 24 or the likeand bent under or on the inside, as shown in Figure 11. Thereupon, theworking parts return to the position indicated.

The drivers 11 are formed according to the shape of the fasteningmembers or 'tastenings, hinges etc., and are provided on the sides withribs which fit in the grooves 22 ot the fastener holders 20.

According to Figure 6, a hinge 27 as per ' For cigar boxes,'receptacles,etc., the lid of which is provided with a rim, as shown in Figure 8, aframe 33 is secured to the baseplate 2,'and'on this frame are disposed,in a di splaceable manner, two anvils 34, on which therim of the lid 29and of the box 24 or of thefrecept'acle or the like rests, as shown inFigure 8,

'Fastenmgs, hinges or the like of a form other than those representedcan, of course,

be attached. According to the distance required between them, the levers8, spindles 9,

guides 10, fastener holder carrying members and the anvils 23or 34 areadjusted.

on the machine body 1 a guide 36 is secured, which has a regulatingscrew 36.

Through the regulation of the latter, the

stroke of the 1ever 4 can be adjusted according. to the thickness ofthecigar boxes, receptacles, etc. "As a result the pressure of thedriver 11' is not too heavy, and the wood, cardboard, etc., of the cigarboxes or the like,

will not split.

.Th 'in'achi'ne can also be used for attaching only one fasteningmember, hinge, etc., at a time. In this case a lever 8, a spindle 9,guide ,lOfete, are brought as near as possible to the bedy 1, and in thecorresponding fastener hol'der 20 only one fastening member, hinge orthe like, is inserted.
